South Korea’s Largest Crypto Exchange Upbit Halts Services After $37 Million Solana Token Breach

2025/11/27 15:40

TLDR

  • Upbit, South Korea’s largest crypto exchange, suspended deposits and withdrawals after detecting unauthorized transactions on November 27, 2025
  • Approximately $37 million worth of Solana network tokens were transferred to unauthorized wallets through a compromised hot wallet
  • Affected tokens include BONK, JTO, USDC, ACS, DRIFT, and other Solana-based assets
  • Upbit will fully reimburse all customers using the exchange’s own assets to cover losses
  • The exchange moved remaining funds to cold storage and froze about $8 million worth of Solayer tokens with law enforcement help

Upbit suspended all digital asset deposits and withdrawals on Thursday morning after detecting irregular activity on its Solana network wallets. The South Korean exchange identified unauthorized transfers totaling approximately 54 billion won, or $37 million.

The breach occurred around 4:42 AM local time on November 27, 2025. Exchange operators detected the irregular withdrawals from a compromised hot wallet address early in the incident.

Dunamu CEO Oh Kyung-seok confirmed the security breach in a public notice. He apologized to users for the service disruption and assured customers that the exchange would handle all losses.

The affected tokens span multiple categories on the Solana network. Meme coins including BONK, MOODENG, and Official Trump were among the compromised assets. Decentralized finance tokens such as Sonic SVM, Access Protocol, JTO, SOL, and Raydium were also transferred.

Other affected assets include DoubleZero, DOOD, Drift, HUMA, Ionet, JUP, LAYER, ME, Pudgy Penguin, and Circle’s USDC stablecoin. The unauthorized transfers moved these tokens to external wallet addresses not designated by Upbit’s internal systems.

Exchange Response and Asset Recovery

Upbit took immediate action after detecting the breach. The exchange transferred all remaining digital assets to cold storage to prevent further unauthorized transactions. Cold storage keeps cryptocurrency offline and away from potential network vulnerabilities.

The exchange worked with law enforcement to initiate on-chain freezing measures. These efforts successfully froze approximately 12 billion won, or $8 million, worth of Solayer tokens related to the incident. Upbit is coordinating with other token projects to attempt additional asset freezes.

Upbit launched a complete security audit of all digital asset transfer systems. The exchange stated it will gradually resume withdrawal services only after confirming system security. Deposit and withdrawal functions remain suspended while the investigation continues.

The exchange emphasized that customers will not bear any financial burden from the breach. Upbit committed to fully reimbursing all affected users using the company’s own assets. This compensation policy aims to protect user funds completely.

The timing of this security incident comes as Upbit’s parent company Dunamu navigates a major corporate change. Naver Financial agreed to absorb Dunamu in a $10.29 billion all-stock deal announced November 26, 2025. The transaction requires regulatory approval and would issue 2.54 new Naver shares for each Dunamu share.

Shocking OpenVPP Partnership Claim Draws Urgent Scrutiny

Shocking OpenVPP Partnership Claim Draws Urgent Scrutiny

The post Shocking OpenVPP Partnership Claim Draws Urgent Scrutiny appeared on BitcoinEthereumNews.com. The cryptocurrency world is buzzing with a recent controversy surrounding a bold OpenVPP partnership claim. This week, OpenVPP (OVPP) announced what it presented as a significant collaboration with the U.S. government in the innovative field of energy tokenization. However, this claim quickly drew the sharp eye of on-chain analyst ZachXBT, who highlighted a swift and official rebuttal that has sent ripples through the digital asset community. What Sparked the OpenVPP Partnership Claim Controversy? The core of the issue revolves around OpenVPP’s assertion of a U.S. government partnership. This kind of collaboration would typically be a monumental endorsement for any private cryptocurrency project, especially given the current regulatory climate. Such a partnership could signify a new era of mainstream adoption and legitimacy for energy tokenization initiatives. OpenVPP initially claimed cooperation with the U.S. government. This alleged partnership was said to be in the domain of energy tokenization. The announcement generated considerable interest and discussion online. ZachXBT, known for his diligent on-chain investigations, was quick to flag the development. He brought attention to the fact that U.S. Securities and Exchange Commission (SEC) Commissioner Hester Peirce had directly addressed the OpenVPP partnership claim. Her response, delivered within hours, was unequivocal and starkly contradicted OpenVPP’s narrative. How Did Regulatory Authorities Respond to the OpenVPP Partnership Claim? Commissioner Hester Peirce’s statement was a crucial turning point in this unfolding story. She clearly stated that the SEC, as an agency, does not engage in partnerships with private cryptocurrency projects. This response effectively dismantled the credibility of OpenVPP’s initial announcement regarding their supposed government collaboration. Peirce’s swift clarification underscores a fundamental principle of regulatory bodies: maintaining impartiality and avoiding endorsements of private entities. Her statement serves as a vital reminder to the crypto community about the official stance of government agencies concerning private ventures. Moreover, ZachXBT’s analysis…

BlackRock boosts AI and US equity exposure in $185 billion models

BlackRock boosts AI and US equity exposure in $185 billion models

The post BlackRock boosts AI and US equity exposure in $185 billion models appeared on BitcoinEthereumNews.com. BlackRock is steering $185 billion worth of model portfolios deeper into US stocks and artificial intelligence. The decision came this week as the asset manager adjusted its entire model suite, increasing its equity allocation and dumping exposure to international developed markets. The firm now sits 2% overweight on stocks, after money moved between several of its biggest exchange-traded funds. This wasn’t a slow shuffle. Billions flowed across multiple ETFs on Tuesday as BlackRock executed the realignment. The iShares S&P 100 ETF (OEF) alone brought in $3.4 billion, the largest single-day haul in its history. The iShares Core S&P 500 ETF (IVV) collected $2.3 billion, while the iShares US Equity Factor Rotation Active ETF (DYNF) added nearly $2 billion. The rebalancing triggered swift inflows and outflows that realigned investor exposure on the back of performance data and macroeconomic outlooks. BlackRock raises equities on strong US earnings The model updates come as BlackRock backs the rally in American stocks, fueled by strong earnings and optimism around rate cuts. In an investment letter obtained by Bloomberg, the firm said US companies have delivered 11% earnings growth since the third quarter of 2024. Meanwhile, earnings across other developed markets barely touched 2%. That gap helped push the decision to drop international holdings in favor of American ones. Michael Gates, lead portfolio manager for BlackRock’s Target Allocation ETF model portfolio suite, said the US market is the only one showing consistency in sales growth, profit delivery, and revisions in analyst forecasts. “The US equity market continues to stand alone in terms of earnings delivery, sales growth and sustainable trends in analyst estimates and revisions,” Michael wrote. He added that non-US developed markets lagged far behind, especially when it came to sales. This week’s changes reflect that position. The move was made ahead of the Federal…

UNI Price Prediction: Critical Support Test at $5.37 – Next Target $7.88 by January 2025

The post UNI Price Prediction: Critical Support Test at $5.37 – Next Target $7.88 by January 2025 appeared on BitcoinEthereumNews.com. Peter Zhang Dec 06, 2025 06:55 UNI price prediction shows critical support test at $5.37 with potential rebound to $7.88 target. Technical analysis reveals oversold conditions setting up recovery. Uniswap (UNI) is trading at a critical juncture as the token tests key support levels following a sharp 7.39% decline in the past 24 hours. With UNI currently priced at $5.51, our comprehensive technical analysis reveals both immediate risks and potential opportunities for the leading decentralized exchange token. UNI Price Prediction Summary • UNI short-term target (1 week): $6.20-$6.50 (+12-18%) • Uniswap medium-term forecast (1 month): $7.50-$8.35 range• Key level to break for bullish continuation: $5.98 (24h high) • Critical support if bearish: $5.37 (immediate support) Recent Uniswap Price Predictions from Analysts Recent analyst predictions show a mixed but cautiously optimistic outlook for UNI. Altpricer’s UNI price prediction targets $7.81 in the short term, citing slight upward momentum despite current volatility. Meanwhile, CoinCodex maintains a more conservative Uniswap forecast with an $8.35 target, though their analysis acknowledges bearish sentiment with key support levels identified at $9.02, $8.69, and $8.43. The consensus among analysts suggests that while immediate pressure exists, the UNI price target range of $7.81-$8.35 represents realistic upside potential once current support levels hold. However, confidence levels remain moderate due to broader market uncertainty and DeFi sector headwinds. UNI Technical Analysis: Setting Up for Potential Recovery The current Uniswap technical analysis reveals several compelling signals that support a cautiously bullish outlook. With UNI trading at $5.51, the token sits precariously close to its immediate support at $5.37, just 2.5% below current levels. The RSI reading of 39.09 indicates UNI is approaching oversold territory without being deeply oversold, suggesting limited downside momentum.
